FREDERIC E. BALDWIN, OF NEW YORK, N. Y.

BURNER FOR OIL-LAMPS.

1 ,oeeaec.

Application filed November 17, 1911.

To all whom it may concern Be it known that I, Fnnnnnro E. BALDWIN, acitizen of the United States, and a resident of New York, county andState of New York, have invented a certain new and useful Improvement inBurners for Oil- Lamps, of which the following is a full, clear, andexact specification.

This invention relates to a class of burners adapted to be used inconjunction with lamps which burn oil especially for lighting purposes.

My invention has for its object primarily to provide a form of burner ordevice designed to be employed upon oil lamps whereby a propercombustion of the fuel products will be maintained when the wick of thelamp is ignited and which is adapted to prevent sutficientheat frombeing generated to volatilize the oil in the lamp-body, which ordinarilyproduces an excess of smoke and frequently a distribution of offensiveodors from the liberation of free gas unless the wick of the lamp islowered suiiiciently to greatly dim the light. This is accompllshedmainly by providing a deflector adapted to supply air to the lower partof the flame where the fuel products transmitted by the wick firstundergo combustion and to provide a second deflector for supplying airto the flame above the first feed of air whereby all excess of gaseousproducts w1ll be consumed by the combustion for producing a light ofunusual brilliaucy.

Another object of the invention is to provide a form of burner adaptedto carry a chimney of large diameter; and to further provide means whichwill permit the lamp to remain lighted when in the currents of strongwinds.

lVith these and other objects in View, the invention will be hereinaftermore particu larly described with reference to the accompanying drawing,which forms a part of this specification, and will then be pointed outin the appended claims.

In the drawing, Figure l is an elevation, partly in section, of one formof lamp with my improved oil burner applied thereto. Fig. 2 is anelevation of a form of lamp suitable for out-door use, and showing theburner as used in conjunction therewith. Fig. 3 is a top plan of theburner taken on the line IIII of Fig. 1, and Fig. 4 is a top plan of thethird air injector used in one form of my burner.

Specification of Letters Patent.

Serial No. 660,894.

The oil burner or device 10 may be used in con unction with the usual orany preferred formof lamp, as 11, having a tube 12 for carrying a wick13 whereby light may be produced within a building or other structure,as shown in Fig. 1, or said burner may be employed upon a lantern, asindicated in Fig. 2, which is especially suitable for use in the openair.

Around the upper port-ion of the wick tube 12 is a deflector 14 forsupplying air to the lower part of the wick when ignited. The deflectorlat has an annular wall 15 which is tapered whereby its lower edge isspaced for some distance from the wick tube, and its upper edge isspaced only a slight distance from the free end of said tube. The loweredge of the annular Wall 15 is rigidly held to the wick tube by a numberof spaced short strips 15 so as to provide a passage 16 for air to beadmitted therethrough and supplied to the lower part of the flame wherethe fuel products transmitted by the wick first undergo combustion. Forthe purpose of supplying additional air to the flame of the wick abovethe first fuel feed so that all excess of gaseous products may beconsumed by the combustion and for producing a light of unusualbrilliancy, a second deflect-or 17 is provided. The second air deflector17 has a curved annular member or oriflced plate 18. The curved orificedplate 18 encircles the annular member 15 of the first deflector, and itsinner edge is spaced from said annular member 15 for providing an airpassage 19. The deflector 17 has a vertical wall 18 through which are anumber of spaced openings 18. A chamber is provided between the wall andthe plate 18. This plate may be placed at any desired height withrespect to the top of the annular member 15 of the first deflector, butis preferably positioned on a different relative plane thereto, in orderto efliciently supply through the passage 19 air to the flame above thefeed of air produced by the first deflector. By varying the position ofthe plate 18 and enlarging or lessening the size of the air passage 19thereof various shapes of the flame of the lamp may be provided asoccasion requires.

In conjunction with my oil burner, a chimney, as 20, may be employed sothat its lower end will rest upon the annular member or orificed plate18, and by using a plate of large size a chimney of unusual diameter maybe used, though it is evident that chimneys of any suitable diameter maybe em ployed by varying the size of said. plate.

When the lamp is used in the open air I prefer to employ a draftinducing hood, as 21, which may be of any well known or preferred form,and as a means to prevent the occurrence of back drafts which extinguishthe light and to prevent the flame from smoking, I provide a third airdeflector 22 which is positioned below the level of the sum when thewick is ignited. The third air deflector 22 has an annular member orring 23 surrmnnling the chimney 20, and said ring is supported so thatcurrents of air will be forced under any condition to enter the airchamber of the wall 18 of the second air injector 17.

In practice I prefer to employ a large chimney upon a lamp having myimproved form of burner, as above described. The volume of heated airtherein when the wick is ignited will induce an exceedingly strong draftat the burner through the medium of the first deflector l t, and thesecond deflector 1'7. Part of the air is fed to the lower part of theflame of the wick where combustion first takes place, and part of theair is supplied to the flame at a higher point than the first feed ofthe air, thus all parts of the flame will receive an ample supply ofoxygen. Moreover, the great volume of air which will pass through thechimney will serve to keep it cool, prevent it from cracking, and permitit to be readily handled with safety when desired.

In the foregoing description I have embodied the preferred form of myinvention, but I donot wish to be understood as limiting myself thereto,as I am aware that modifications may be made therein without departingfrom the principle or sacrificing any of the advantages of thisinvention, there fore I reserve to myself the right to make such changesas fairly fall within the scope thereof.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, with a lamp-body, and a wick-tubecarried thereby, of an annulus provided with air inlet-s and surroundingthe wick-tube, an annular deflector carried by the said annulus, and atapered deflector surrounding the Wicktube and having its narrowerportion above the wick tube and projecting above the annular deflectorthrough the central opening therein, said central opening being largeenough to allow the passage of air around the tapered deflector.

2. The combination, with a lampbody, and a wick-tube carried thereby, ofan annular perforated chimney-support carried by the lamp-body andsurrounding the wicktube. an annular incurved deflector carried by thechii'nney-support and having a cen tral opening, a tapered deflectormounted on the wick-tube and having its narrower portion above thewick-tube and projecting above the central opening in the annularincurred deflector, and a chimney carried by said chimney-support andsurrounding both deflectors.

The combination, with a lamp-body, and a wick-tube carried thereby, ofan annular perforated chimney-support carried by the lamp-body andsurrounding the wicktube, an annular incurved deflector carried by thechimney-support and having a cen tral opening, a tapered deflectormounted on the wick-tube and having its narrower portion above thewick-tube and projecting above the central opening in the annulariucurved deflector, a chimney carried by said chimney-support andsurrounding both deflectors, and an exterior deflector surrounding thechimney-support and the lower end of the chimney and arranged to deflectthe outer air to the openings in the chimneysupport.

i. The combination, with a lamp-body, and a wick-tube carried thereby,of an annular perforated chimney-support carried by the lamp-body andsurrounding the wick tube, an annular incurved deflector carried by thechimney-support and having a central opening, a tapered deflectormounted on the wick-tube and having its narrower portion above thewick-tube and projecting above the central opening in the annularincurved deflector, a chimney carried by said chimney-support andsurrounding both deflectors, and an exterior deflector arranged todeflect the outer air to the openings in the chimney-support.
